The IDF said it targeted dozens of Hezbollah targets early Sunday. Some countries urged citizens to leave Lebanon, as it braces for a possible ground invasion.

Israel says it has killed Hassan Nasrallah, Hezbollah's powerful leader. The Iran-backed militant group has not confirmed his death. Israel continues strikes across Lebanon.

Israel and Hezbollah are exchanging hundreds of cross-border strikes in the wake of the shocking explosions of wireless devices across Lebanon last week. Small-scale operations or "border movements" into Lebanon to take out Hezbollah positions right on the border have begun or are about to, according to two U.S. officials.
